Table 2.
Summary of the mechanical, and solvent resistance properties of the six tested systems. Maximal conversions after thermal annealing are also included. 10 % HClaq and 10 % NaOHaq were selected as the media for hydrolytic tests. +/- at each value stands for sample mass gain/loss. Brackets show standard deviations values.
